In connection with swinging sashes, vents or other closures, andparticularly those which swing outwardly and wlth whlch fixed screensare employed, it is very desirable that means be provided for positivelylocking the closures when in open position, for there is danger whenhigh winds or sudden gusts oc cur, that they will be slammed sometimeswith suflicient force to break the glass or the hinges.

The object of the present invention is to provide a structure of thischaracter which is highly effective, and at the same time is extremelysimple, so that the sash may be held in various positions, and even ifit should occur that in a certain position it is not positively locked,it can only move a short distance before it becomes so locked.

In the embodiment disclosed, the win dowframe is shown at 10, and hingedto one side of the same, as illustrated at 11 in Figure 1, is a swingingsash or vent 12. The frame and vent are shown as of deformed metal,though the material of which they are constructed is relativelyunimportant.

Secured to the inner side of the lower cross bar of the frame is acasing which consists of a base plate or bottom wall 13 havingupstanding ears 14 on its rear side engaged by screws 15 that serve tosecure the casing to theinner side of the frame bar. The distancebetween theears 14 as shown. in Figure '3 marks the length of a slot 16formed in the framebar 10. A top wall'17 is provided with side flanges18 forming the side walls of the casing and these flanges have suitablelugs 19 that pass through openings 20 in the base plate 13 and areupset, thereby securing the casing members together. The side walls 18have portions cut away to provide an opening 21", which with the spacebetween the ears 14 of the base plate, provides a transverse passagewaythrough the casing.

In this passageway isslidably and swingingly mounted a sash-holding bar22 which is channeled as shown at 23 and at its outer end has a pivotalconnection 24 with a bracket 25 secured to the swinging sash 12. The bar22 is guided in its movement through the easing by an upstanding post 26fixed to the bottom wall 13 and having a socket 27 opening through itsupper end. This post as clearly shown in Figures 4 and 8 is engaged inthe channel of the bar and therefore constitutes not only a slide guidebut also one on which the bar has a pivotal movement. The inner end ofthe bar 22 is preferably provided with an upstanding finger piece28f0rmed by an angle piece, one arm 29 of which is fitted in the end'ofthe channel 23 of the bar 22 and is secured by any suitablemeans as ascrew The top wall .17 has fixed thereto an upstanding cylindrical shell31 in which is slidably mounteda plunger 32 carried by a stem 33 thatprojects above the shell and has a finger piece 34. A coiled spring 35,located in-the shell 31 and pressing on the plunger 32, urges itdownwardly. The lower end of the plunger is in the form of a stud 36that is adapted to pass through any of a series of openings 37 formed inthe holding bar 22 at various points along the same. The stud 36moreover is adapted to engage in the socket'27 of the post 26, as willbe clear by refer-e ,ence to Figure 4.

It will beevident that with this structure, if the plunger is raised,by. raising the finger piece 34the stud 36 Willbe disengaged'from thesocket 27 and will be elevated above the bar 22. Consequently the barcan then be freely operated and the sash swung in either direction. Whena desired position has been obtained and the plunger is released, if oneof the openings 37 of the bar is in line with the stud 36, said studwill pass through such opening and into the socket 27. The bar will thusbe positively looked as clearly shown in Figure 4 and the sash will bejust as positively held against swinging movement. Should it happen thatnone of the openings 87 is in line with the plunger, said plunger willthen rest on the bar, but it will be evident that if the sash moves thebar will be correspondingly moved and the first opening that registerswith thelstud will receive the same and consequently automatically lockthe sash against further movement. p

The structure is simple and effective and not onlycan be manufactured atrelatively small cost, butis readily installed.

I From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in. the art without further description, and it'will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

What I claim, is:

way, and a plunger mounted in the casing and engaging the bar to secureit.

A closure operator and lock comprising a mounting member having apassageway, a post located in the passageway, a channeled closureoperating and holding bar slidably extending through the passageway andhav ing its channel slidably receiving the post, and means that engagesthe bar to secure it against movement.
